Process Step:
Process Description:
Each TM image to be used in the classification process was reviewed for database consistency with land use/land cover maps and corrected for atmospheric haze effects as needed. The images were normalized and the first three rotations (brightness, greenness, wetness) of the tasseled cap algorithm were applied. The tasseled-cap transformation which provides a mechanism for data reduction and enhanced image interpretation is computed for Natural areas were isolated from the high reflectance values of urban and agricultural areas prior to classification. Using the 'Urban and Ag' masks with the tasseled cap image, the unsupervised classification routine (explained below) was used to create a 10 to 25 Class image of the masked area. The classes were visually compared to the tasseled cap imagery and those identified as natural areas were included with the areas defined by the 'Natural Areas Mask.' ERDAS Imagine's iterative unsupervised classification algorithm (ISODATA) was applied to the tasseled cap plus raw bands 2,3,4, and 5, under the 'Natural Areas Mask' to create spectral signatures. These signatures were then used with the minimum-distance-to-mean classifier to create a classified image. The classified image was stratified and the classes were combined or split further using a knowledge based "cluster busting" method. Refer to the Landcover Mapping chapter of the FLGap Final Report for detailed description.
